Abstract :
A CMOS erasable programmable logic device (EPLD) optimized for microprocessor peripheral and bus control applications is described. In addition to a general-purpose EPLD core and 52 user-configurable registers, the dedicated peripheral I/O logic can be programmed by the control macrocells to interface directly to all known microprocessor families. An I/O bus port with 24-mA drive capability allows direct connection to a microprocessor bus
